Installation
Refer to Fig. A, B and C for installation directions.
- Before installation, check if the plumbing system has been set-up according to the
applicable plumbing code.
- Avoid all kinds of tensions by using a wall bracket. Should the use of the wall bracket
be impossible, the installer (qualified and licensed personnel) shall be responsible for
the most appropriate installation avoiding tensions which may affect the filter's integrity.
- Connect the inlet to the product's side with the arrow IN and the oulet to the side
with the arrow OUT (Fig. B).
- Connect to pipes using tapered (conical) fittings ONLY in the case of NPT
marked filter housing and/or in the case of filter housing specified as NPT in
the label affixed in the package of the product. Preferably connect to pipes
using flexible hoses.
- Connect to pipes using BSPP (cylindrical) fittings in the case the filter housing is not
marked NPT or not specified as NPT in the package label. Preferably connect to pipes
using flexible hoses.
- Use only sealing tape as a sealant for the connections.
- The installation of a By-pass is recommended (see Fig. C).
- Connect a rubber tube to the drain funnel (or hose fitting) at the base of the filter,
secure with a clamp and have it discharge into the drain (see figures D1 and D2).
The drain point must be lower than the drain funnel or hose fitting. The rubber tube
must not be more than 2 metres long.
Avoid bending or pinching the rubber tube reinforced with canvas: this could
generate counter-pressure against the drain with consequent malfunctions.
